A window includes a base layer and a hard coating layer on the base layer. The hard coating layer includes a first layer on the base layer and of a first thickness, and a second layer on the first layer and of a second thickness. The second layer includes an antistatic agent. The hard coating layer has a hardness reduction rate of 50 percent (%) or less expressed as follows.In the equation above, H is a hardness reduction rate (%) of a target layer, D1 is a hardness reduction rate measured from the target layer at a temperature of 60 degrees Celsius (° C.) with a relative humidity of 93%, and D2 is a hardness reduction rate measured from the target layer at a room temperature with a relative humidity of 30%.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The window of claim 1, wherein the antistatic agent includes a Sb-based material.
3. The window of claim 2, wherein an atomic ratio of Sb in the second layer is greater than an atomic ratio of Sb in the first layer.
4. The window of claim 1, wherein the first thickness is ⅔ to 9 times the second thickness.
6. The window of claim 1, wherein the hard coating layer is in contact with the base layer.
8. The window of claim 1, wherein the hard coating layer further includes the antistatic agent, a nanosilica sol, and a translucent resin.
9. The window of claim 1, wherein the window folds with reference to a predetermined bending axis.
10. The window of claim 1, wherein the base layer includes a polymer film, a plastic substrate, or a glass.
11. The window of claim 1, wherein a thickness of the hard coating layer is in a range between 5 micrometers and 20 micrometers.
13. The method of claim 12, wherein the hard-coating composition solution includes an antistatic agent, a nanosilica sol, a translucent resin, a photoinitiator, and a solvent.
14. The method of claim 13, wherein the antistatic agent is distributed to 10 percent to 60 percent of a thickness of the hard coating layer in a direction from a top surface of the hard coating layer toward a bottom surface of the hard coating layer.
15. The method of claim 12, wherein curing the hard-coating composition solution includes irradiating an ultraviolet ray into the hard-coating composition solution.
16. The method of claim 12, wherein the base layer includes a polymer film, a plastic substrate, or a glass.
17. The method of claim 12, wherein a thickness of the hard coating layer is in a range between 5 micrometers and 20 micrometers.
19. The display device of claim 18, wherein the antistatic agent includes a Sb-based material.
20. The display device of claim 18, wherein the first thickness is ⅔ to 9 times the second thickness.
